Based on another thread that I saw here, I've been thinking about this sort of ecosystem for a while...I set this up about 10 days ago, but haven't had a chance to post pics before now.
I bought a 1 gallon jar from amazon - http://www.amazon.co...l...5485&sr=8-1
I added some dead sand, a nice-sized piece of rock, a smaller chunk of live rock, some chaeto from my fuge, some snails, a pair of asterina stars (you can see one in front of the chaeto if you look closely), and a couple of "core-samples" of sand and muck taken from the bottom of my 10G tank with the turkey baster.
I'm not sure of the longterm viability of this system because of the temp that we keep our house, and the lack of sunlight in Northern NY in wintertime, but so far things seem to be ticking along ok...I have a plant-based jar that's been sealed for years, and thrives in my house with only an occasional dusting...this SW jar will have to make it without additional input of heat or light, besides what it gets from the environment of my house.
